From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I disagree on the aliases. I'd recommend using almost none. It builds competence with the commands on all systems even without your special .bashrc. It'll be easier to write scipts and change shells as well.
I use fish abbreviations. Unlike bash/zsh aliases, they expand when you press space or enter. This way you see the original command every time you use the alias, and you can edit as well. This should lighten the concern you have a bit. Your concern is something that sysadmins keep in mind e.g. default vim bindings so you are always comfortable on any server. However for desktop use I don't think leaving the speed and comfort on table is worth it. Most desktop users only use their own systems anyway.
It's about building muscle memory as well though. You are right that many home-gamers will probably never be without their customizations though. But if you do re-installs, setup VMs, try new distros, etc. it's beneficial.
Just my opinion though.
That really depends on what you're doing. It's only really useful when you're regularly SSH-ing into other machines for work. Otherwise you're wasting time every day so that you might save a second once every few years.
